Pyrene-Terminated Tin Sulfide Clusters: Optical Properties and Deposition on a Metal Surface.


ABSTRACT: Herein, we present the synthesis of two pyrene-functionalized clusters, [(Rpyr Sn)4 S6 ]?2?CH2 Cl2 (4) and [(Rpyr Sn)4 Sn2 S10 ]?n?CH2 Cl2 (n=4, 5?a; n=2, 5?b; Rpyr =CMe2 CH2 C(Me)N-NC(H)C16 H9 ), both of which form in reactions of the organotin sulfide cluster [(RN Sn)4 S6 ] (C; RN =CMe2 CH2 C(Me)N-NH2 ) with the well-known fluorescent dye 1-pyrenecarboxaldehyde (B). In contrast, reactions using an organotin sulfide cluster with another core structure, [(RN Sn)3 S4 Cl] (A), leads to formation of small molecular fragments, [(Rpyr Cl2 Sn)2 S] (1), (pyren-1-ylmethylene)hydrazine (2), and 1,2-bis(pyren-1-ylmethylene)hydrazine (3). Besides synthesis and structures of the new compounds, we report the influence of the inorganic core on the optical properties of the dye, which was analyzed exemplarily for compound?5?a via absorption and fluorescence spectroscopy. This cluster was also used for exploring the potential of such non-volatile clusters for deposition on a metal surface under vacuum conditions.
